Kernel crashes with ipsec connection over ppp Description of problem: I get kernel crashes when I set up an ipsec connection over ppp on a Huawei E220 HSDPA USB modem in the Fedora 9 beta. If I try to copy a large file over the ipsec connection the machine hangs completely within a few seconds with the caps lock and scroll lock lights blinking. I have an ipsec.conf file that looks like this, somewhat censored: version 2.0 config setup protostack=netkey nat_traversal=yes conn xxx left=xxx.xxx.xxx.xxx leftid=@xxx right=xxx.xxx.xxx.xxx rightsubnet=xxx.xxx.xxx.xxx/24 rightid=@xxx auto=start aggrmode=yes authby=secret pfs=no ike=3des-sha1-modp1024 include /etc/ipsec.d/*.conf If I set up an identical ipsec connection on an ethernet interface instead it works without problems, and non-ipsec traffic on the ppp connection doesn't cause any problems. I have seen a few different kernel panic messages, attaching a file with three samples. Version-Release number of selected component (if applicable): kernel-2.6.25-14.fc9.x86_64 How reproducible: Crashes within a few seconds every time. Steps to Reproduce: 1. Set up ipsec connection over ppp connection over HSDPA USB modem. 2. Copy a large file over the connection using scp. Actual results: Kernel crash. Expected results: No kernel crash.
Created attachment 304566 [details] Sample panic messages.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Is this still reproducible with the latest kernel? Thanks!
Seems to be fixed. I can't reproduce with neither kernel-2.6.27.9-73.fc9.x86_64 nor kernel-2.6.27.9-159.fc10.x86_64.
